This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.

The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:

  Device (AHC0) // AHCI Controller
  {
    Name(_HID, "AMDI0600")
    Name (_CCA, 1)
    Name (_CLS, Package (3)
    {
      0x01, // Base Class: Mass Storage
      0x06, // Sub-Class: serial ATA
      0x01, // Interface: AHCI
    })
    Name (_CRS, ResourceTemplate ()
    {
      Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
      Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
    })
  }

Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.

Pull ARM SoC cleanups from Kevin Hilman:
 "A relatively small setup of cleanups this time around, and similar to
  last time the bulk of it is removal of legacy board support:

   - OMAP: removal of legacy (non-DT) booting for several platforms

   - i.MX: remove some legacy board files"

Pull libata updates from Tejun Heo:

 - a number of libata core changes to better support NCQ TRIM.

 - ahci now supports MSI-X in single IRQ mode to support a new
   controller which doesn't implement MSI or INTX.

 - ahci now supports edge-triggered IRQ mode to support a new controller
   which for some odd reason did edge-triggered IRQ.

 - the usual controller support additions and changes.

Use syscon/regmap to configure the smc. This allows to avoid using
at91sam9_smc.h and to compile the driver in a multiplatform configuration.

The driver will still not probe until the proper DT bindings are added. That
binding will include an atmel,smc property that is a phandle to the SMC the CF
controller is connected to.

Since sata_dwc_460ex.c was moved to generic DMA driver we have to ensure that

The SCC PATA interface is only used by celleb.
celleb has been dropped [1], so drop the drivers.

Commit 84683a7e081f ("sata_dwc_460ex: enable COMPILE_TEST for the
driver") enabled this driver for non-ppc460-ex platforms, but it was
then disabled for ARM and ARM64 by commit 2de5a9c004e9 ("sata_dwc_460ex:
disable compilation on ARM and ARM64") because it's too noisy and
broken.

This disabled is entirely, because it's too noisy on x86-64 too, and
there's no point in disabling architectures one by one.  At a minimum,
the code isn't 64-bit clean, and even on 32-bit it is questionable
whether it makes sense.
